Description

Method and device for controlling a V2X message transmission service for a vehicle

The present invention relates to methods and devices for controlling the transmission or communication of so-called V2X messages (from the English “Vehicle-to-Everything” or in French “Véhicule vers tout”) for vehicles, for example but not exclusively for vehicles. automobile. The present invention also relates to a method and a device for identifying a vehicle. The present invention also relates to a method and a device for interrupting a V2X message communication service for a vehicle.

Technology background

To improve safety on the roads, new technologies are emerging that allow the exchange of information between vehicles and/or between vehicles and the infrastructure surrounding them. Thus, new information and communication technologies applied to the field of transport have appeared, such as ITS G5 (from the English “Intelligent Transportation System G5” or in French “Système de transport intelligent G5”) in Europe or DSRC (from the English “Dedicated Short Range Communications” or in French “Communications dedicated to short range”) in the United States of America which are both based on the IEEE 802.11p standard or even technology based on cellular networks called C-V2X (from the English “Cellular – Vehicle to Everything” or in French “Cellulaire – Véhicule vers tout”) which is based on 4G based on LTE (from the English “Long Term Evolution” or in French “Long-term evolution”) and soon 5G.

As part of these technologies, control and/or signaling messages are communicated between vehicles in the same environment, for example to inform other vehicles of communication system configuration data or traffic parameters. The transmission of such messages by a given vehicle thus provides information on the presence of this vehicle to other vehicles.

This can cause certain problems depending on the situation. For example, a law enforcement vehicle during an intervention might wish to hide its presence from other vehicles.

Summary of the present invention

An object of the present invention is to solve at least one of the problems of the technological background described above.

Another object of the present invention is to mask the presence of a vehicle from other vehicles.

According to a first aspect, the present invention relates to a method for controlling a message transmission service according to a vehicle-to-everything communication mode, called V2X, the method being implemented by a vehicle and comprising the following steps:
- determination of a so-called vehicle intervention mode based on information received from at least one device on board the vehicle;
- transmission, to a remote device via a wireless link, of a request to deactivate the service, the request comprising first data representative of vehicle identification;
- reception, from the remote device via the wireless connection, of second data representing authorization or prohibition of deactivation of the service;
- service deactivation control based on second data.

Transmitting a request to deactivate the transmission of V2X messages including vehicle identification data allows the remote device to check whether or not this vehicle is authorized to deactivate the service. Receiving authorization or prohibition data to deactivate the service makes it possible to automatically control the deactivation of the service according to the authorization or prohibition data received.

Thus, according to the invention, only authorized vehicles (for example gendarmerie or police vehicles) can deactivate the communication of V2X messages to hide their presence from other vehicles when they are on intervention.

According to a variant, the second data is representative of an authorization to deactivate the service when the first data belongs to identification data of a first set of vehicles authorized to interrupt any message communication according to the V2X communication mode at the destination of a second set of vehicles, the deactivation being implemented when the second data is representative of authorization to deactivate the service.

According to another variant, each vehicle of the first set of vehicles corresponds to a type of vehicle belonging to the police type or the gendarmerie type and each vehicle of the second set corresponds to a civilian type vehicle.

According to an additional variant, the first data correspond to data from an identification certificate issued by a public key infrastructure, the remote device belonging to the public key infrastructure.

According to yet another variant, the method further comprises a rendering of data representative of deactivation of the service by at least one rendering device on board the vehicle.

According to an additional variant, the information belongs to a set of information comprising:
- information representative of the operation of a vehicle rotating beacon;
- information representative of the operation of a vehicle siren;
- information representative of activation of a so-called standardized mode of the vehicle.

According to another variant, the method further comprises a step of reactivating the service following deactivation of the service based on data representative of a reactivation command.

According to a second aspect, the present invention relates to a device for controlling a message transmission service according to a vehicle-to-everything communication mode, called V2X, the device comprising a memory associated with a processor configured for implementing the steps of the process according to the first aspect of the present invention.

According to a third aspect, the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention.

According to a fourth aspect, the present invention relates to a computer program which comprises instructions adapted for the execution of the steps of the method according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

Such a computer program can use any programming language, and be in the form of a source code, an object code, or an intermediate code between a source code and an object code, such as in partially compiled form, or in any other desirable form.

According to a fifth aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for executing the steps of the method according to the first aspect of the present invention.

On the one hand, the recording medium can be any entity or device capable of storing the program. For example, the medium may comprise a storage means, such as a ROM memory, a CD-ROM or a ROM memory of the microelectronic circuit type, or even a magnetic recording means or a hard disk.

On the other hand, this recording medium can also be a transmissible medium such as an electrical or optical signal, such a signal being able to be conveyed via an electrical or optical cable, by conventional or terrestrial radio or by self-directed laser beam or by other ways. The computer program according to the present invention can in particular be downloaded onto an Internet type network.

Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to execute or to be used in executing the method in question.

Description of the implementation examples

A method and a device for controlling a V2X message transmission service for vehicles will now be described in what follows with reference jointly to Figures 1 to 3. The same elements are identified with the same reference signs throughout of the description which follows.

According to a particular and non-limiting example of embodiment of the present invention, the control of a message transmission service (s) according to a vehicle-to-everything communication mode, called V2X, for example for the transmission of signaling messages of the type CAM (from the English “Cooperative Awareness Message” or in French “Message d’annonce coopératif”) and/or DENM (from the English “Decentralized Environmental Notification Message” or in French “Message de notification Environnementale Décentrée”), includes determining a so-called vehicle intervention mode implementing this control based on information received from one or more devices on board the vehicle. A vehicle intervention mode corresponds to a mode depending on the vehicle carrying out a particular operation or mission.

A request for authorization to deactivate the service is transmitted by the vehicle to a remote device via a wireless link. Such a remote device corresponds for example to a “cloud” server (or “cloud” in French). Such a server corresponds for example to a PKI server (from the English “Public Key Infrastructure” or in French “Public Key Infrastructure”). The request advantageously includes first data representative of a vehicle identifier, which first data correspond for example to a vehicle identification certificate issued by a PKI certification authority.

In return, the vehicle receives from the remote device, via the wireless connection, second data representing authorization or prohibition of deactivation of the service.

The V2X message transmission service is then automatically deactivated or kept activated depending on the second data received.

There schematically illustrates a vehicle communication system 1, according to a particular and non-limiting embodiment of the present invention.

There illustrates a first vehicle 11 and a second vehicle 12 traveling in a road environment. The first vehicle 11 and the second vehicle 12 each carry, for example, a communication device for transmitting and receiving data intended for another vehicle and/or a server of a network infrastructure. Each communication device can be likened to a node of a network, for example an ad hoc wireless network.

The network infrastructure comprises for example one or more communication devices 110 each corresponding for example to an antenna of a cellular network of the LTE 4G or 5G type or to a UBR (“Roadside Unit”).

The vehicles 11 and 12 communicate advantageously using a so-called V2X communication system, for example based on the 3GPP LTE-V or IEEE 802.11p standards of ITS G5. In such a V2X communication system, each vehicle has a node to enable V2V vehicle-to-vehicle (vehicle-to-vehicle) and vehicle-to-vehicle-to-infrastructure (V2I) communication. -infrastructure) and/or vehicle-to-pedestrian V2P.

In such a V2X communication system, 2 or more vehicles each carrying a node can communicate with each other as part of vehicle-to-vehicle V2V communication; each vehicle can communicate with the infrastructure set up as part of vehicle-to-infrastructure V2I communication; each vehicle can communicate with one or more pedestrians equipped with mobile devices (for example a smartphone) as part of vehicle-to-pedestrian V2P communication.

Each communication device (antenna or UBR) 110 is advantageously connected to one or more remote servers or to the “cloud” 100 (or in French “cloud”) via a wired and/or wireless connection. Each antenna or UBR 110 can thus act as a relay between the “cloud” 100 and the first vehicle 11 and/or the second vehicle 12.

According to a variant, the first vehicle 11 and the second vehicle 12 communicate with each other according to a direct communication mode, for example conforming to:
- ITS G5 in Europe or DSRC (Dedicated Short Range Communications) in the United States of America, both of which are based on the IEEE 802.11p standard; Or
- LTE-V Mode 4 (from the English “Long-Term Evolution – Vehicle Mode 4” or in French “Long-Term Evolution – Vehicle Mode 4”) which allows V2V communications, also called “sidelink” communications (or in French “sidelink”)) based on a direct LTE communications interface called PC5; such technology is described for example in the article entitled “Analytical Models of the Performance of C-V2X Mode 4 Vehicular Communications”, written by Manuel Gonzalez-Martin, Miguel Sepulcre, Rafael Molina-Masegosa and Javier Gozalvez, and published in 2018 .

A certification authority 101 of a PKI is accessible via the Internet and/or the “cloud” 100 by the first vehicle 11 to, for example, receive one or more identification certificates from the first vehicle 11 and/or to receive certificates pseudonyms (also called anonymous certificates or authorization tickets) for V2V or V2I type communications for example. An identification certificate of the first vehicle 11 corresponds for example to a long-term certificate, called LTC (from the English "Long-Term Cerificate") issued by a long-term certification authority, called LTCA (from the English " Long-Term Certificate Authority). A pseudonymous certificate is, for example, valid for a specific period of time, for example a few days or a week. A pseudonymous certificate is issued by a pseudonym certification authority, called the PKI Pseudonym Certification Authority. The PCA issues the pseudonymous certificate to the first vehicle 11 (also called ITS station, or ITS-S (from English “Intelligent Transportation System – Station”)) which has one or more long-term LTC certificates). Such an infrastructure is for example described in the ETSI TR 103 415 v1.1.1 document of April 2018.

In a classic mode of operation, the first vehicle 11 selects an LTC certificate or a pseudonymous certificate for the transmission of V2X messages, for example for CAM messages (from the English “Cooperative Awareness Message” or in French “Message d’annonce cooperative") and/or DENM (from the English "Decentralized Environmental Notification Message" or in French "Message de notification Environnemental Décentrée").

A problem associated with this classic mode of operation is that the first vehicle 11 reveals its presence to other vehicles, for example the second vehicle 12, by the simple transmission of V2X messages. This problem is particularly present for certain types of vehicles, for example law enforcement vehicles such as the police and gendarmerie, which may wish to mask their presence from other vehicles in particular situations.

A process for controlling a message transmission service according to a vehicle-to-everything communication mode, called V2X, is advantageously implemented by the first vehicle 11. The process is for example implemented by one or more devices embedded in the first vehicle 11, for example by one or more processors of one or more computers.

In a first operation, the first vehicle 11 determines a current mode of the first vehicle 11, for example from a list of determined modes, from data or information received from one or more devices on board the first vehicle 11.

An on-board device corresponds for example to a computer or to a sensor on-board in the first vehicle and transmitting data or information to the computer in charge of the control process of the V2X message transmission service.

Thus, the computer in charge of controlling the V2X message transmission service is connected in communication with other computers and sensors of the first vehicle 11. These computers and sensors form the on-board system of the first vehicle 11 with for example a TCU unit ( from English “Telematic Control Unit” or in French “unit decontrol telematique”). These computers, sensors, TCU unit, communication antennas connected to the TCU unit form for example a multiplexed architecture for the production of different services useful for the proper functioning of the vehicle and to assist the driver and/or passengers of the vehicle in the control of the first vehicle 11, for example by controlling the V2X transmission or communication service. The computers and the TCU unit communicate and exchange data with each other via one or more computer buses, for example a CAN data bus type communication bus (from the English “Controller Area Network” or in French “Réseau de controllers”), CAN FD (from the English “Controller Area Network Flexible Data-Rate” or in French “Network of controllers with flexible data rate”), FlexRay (according to the ISO 17458 standard) or Ethernet ( according to ISO/IEC 802-3).

The list of modes includes in particular a so-called intervention mode corresponding to a mode during the first vehicle 11 performs a specific action or operation. The action or operation determined varies, for example, depending on the type of vehicle.

When the first vehicle 11 corresponds to a police or gendarmerie vehicle, the intervention mode corresponds to a mode during which the first vehicle 11 carries out road checks, follows or searches for another vehicle, is on its way to a determined location with activation of the siren or flashing light, etc.

The mode of intervention is for example determined from one or more of the following information or data:
- information/data representative of the operation of a rotating beacon of the first vehicle 11, such information being obtained for example from a computer controlling the rotating beacon; and or
- information/data representative of the operation of a siren of the first vehicle 11, such information being obtained for example from a computer controlling the siren and/or a microphone detecting the activation of the siren; and or
- information/data representative of activation of a so-called standard mode of the first vehicle 11, a standard mode being for example activated by manual control via a man-machine interface, called HMI, (touch screen, control button, etc. .), the information of the standardized mode being obtained from the computer in charge of the HMI (for example the IVI computer (from the English “In-Vehicle Infotainment” or in French “Infodivertissement onboard”)).

In a second operation, when the intervention mode has been determined or detected, the first vehicle 11 transmits to a remote device, for example a “cloud” server 100, a request to deactivate the V2X transmission service of the first vehicle 11 (also called request for authorization to deactivate the V2X communication service or system), the request comprising first data representative of identification of the first vehicle 11.

This request is for example transmitted according to the V2X communication mode, for example according to a V2I mode via one or more relay devices such as the antenna 110.

According to another example, this request is transmitted using a wireless communication mode based on a terrestrial cellular network such as the 4G or 5G mobile telephone network.

The first data identifying the first vehicle 11 correspond for example to a certificate issued by the certification authority 101 to identify the first vehicle 11.

According to another example, the first data identifying the first vehicle 11 correspond to a certificate issued by the certification authority 101 to identify a category or type of vehicle, for example police vehicles, gendarmerie vehicles or vehicles of another law enforcement agency.

In a third operation, the remote device (for example a computer or a server of the certification authority 101) implements a verification of the rights of the first vehicle 11 to interrupt or deactivate the transmission of V2X messages, for example to deactivate any V2X communication or only part of the V2X messages, for example only CAM and/or DENM type messages.

The verification of the rights of the first vehicle 11 is advantageously based on the first data identifying the first vehicle 11.

The remote device checks for example the presence of the identifiers of the first vehicle 11 in a list of vehicle identifiers authorized to deactivate the transmission of V2X messages, for example to all other vehicles or to a category of determined vehicles (for example a second set of vehicles corresponding to civilian vehicles, that is to say vehicles not belonging to the police and/or firefighters for example). The authorized vehicles belong, for example, to a first set of determined vehicles. Each vehicle of this first set is authorized to deactivate the on-board V2X communication service or system, for example to suppress any transmission of V2X messages or part of the V2X messages, for example to each vehicle of the second set or so more general for any other vehicle. Such a list is for example stored in a database which the certification authority accesses. Such a database is for example controlled by the certification authority 101. Such a database stores for example all of the certificates identifying each vehicle of the first set, that is to say each vehicle authorized to deactivate the V2X transmission service, with for example next to each authorized vehicle identifier, one or more deactivation rights with an associated deactivation level (total or partial deactivation, for all vehicles or for a particular set of vehicles, for example the second set).

The vehicles authorized to deactivate the on-board communication service or system correspond for example to vehicles identified as belonging to a particular vehicle type or to a particular category, for example the police or the gendarmerie.

Once the rights of the first vehicle 11 have been verified by the remote device 101, the remote device transmits to the first vehicle 11 via the wireless link second data representative of:
- an authorization to deactivate the V2X message transmission service or system (when the first vehicle 11 belongs to all of the vehicles identified as being authorized); Or
- a ban on deactivating the V2X message transmission service or system (when the first vehicle 11 does not belong to all of the vehicles identified as being authorized).

In a fourth operation, the first vehicle 11 receives the second data from the remote device via the wireless link, for example according to the V2X communication mode, for example according to an I2V mode (from the English “Infrastructure-to-Vehicle” or in French “Infrastructure towards vehicle”).

When the second data is representative of an authorization to deactivate the V2X message transmission service, the computer in charge of the process controls the deactivation of the service by transmitting an ad-hoc request to the TCU unit and/or to the computer in charge to control V2X transmission.

When the second data represents a prohibition on deactivating the V2X message transmission service, the computer in charge of the process does not perform any particular operation and the V2X message transmission service remains activated.

In a fifth operation, information representative of the deactivation of the V2X transmission service is provided by the first vehicle 11 when the service is deactivated, for example by a computer of the on-board system of the first vehicle 11, for example by the IVI computer.

The rendering includes for example a display of a message, on a display screen embedded in the first vehicle 11, informing the passenger(s) of the first vehicle 11 that the transmission of V2X messages is deactivated or interrupted.

According to a variant embodiment, the rendering includes a speech synthesis rendering of the message via one or more speakers on board the first vehicle 11.

Such a process thus allows an authorized or authorized vehicle (for example a police or gendarmerie vehicle) to switch to a hidden or ghost mode by interrupting the transmission of V2X messages, in particular to civilian vehicles. At the same time, the process prohibits unauthorized vehicles from entering such a hidden or ghost mode.

The masked or ghost mode makes it possible to improve the safety of the police or gendarmes when they are in intervention, the discretion of the first vehicle 11 when the latter is in intervention to best ensure the intervention missions.

According to a particular embodiment, the reception of V2X messages transmitted by the other vehicles is kept activated while the transmission of V2X messages is deactivated by the first vehicle 11.

In a sixth operation, the V2X message transmission service is reactivated following deactivation by:
- reception of data or information representative of manual activation of the service, for example by entering a command via the on-board HMI or by pressing a control button arranged in the passenger compartment of the first vehicle 11; and or
- reception of data or information representative of an end of intervention mode (passage into a different mode, for example into a normal circulation mode), the end of the intervention mode being for example automatically detected when the rotating beacon is stopped and/or when the siren is stopped; and or
- reception of data or information representative of stopping the engine of the first vehicle 11.
